BACKGROUND

Dust, pollen, pet dander, mold spores, smoke particles, and volatile organic compounds, among others, can be found as airborne contaminants. In general, such airborne contaminants reduce the quality of air inhaled and can also pose a health risk. In some cases, such contaminants also act as allergens that trigger certain allergies. Air purifiers can be used to reduce the concentration of these airborne contaminants and thereby reduce the amount of contaminants that are inhaled.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the scope of the subject matter presented here.

Referring generally to the figures, various embodiments of systems, methods, and computer readable media for sleep zone air treatment are shown and described. Various airborne contaminants (e.g., dust, pollen, pet dander, mold spores, smoke particles, volatile organic compounds, etc.) reduce the quality of air inhaled. Based on a recommended average amount of sleep-per-day required for adults (e.g., 7-9 hours), adults spend approximately a third of their time relatively stationary (e.g., in a bed) while sleeping. By utilizing the air control devices and processing circuits as described herein, air inhaled by an individual may be “polished” (i.e. treated) to regulate and alter the air's composition such that higher quality air is delivered as the individual sleeps. In this manner, the individual can inhale an increased percentage of higher quality air. Because a bed (or couch, chair, other sleeping/sitting zone, etc.) is typically a relatively small and stationary target environment, polished air may be directed to the area of air-intake of the individual. In addition to being compositionally controlled, such polished air may also be temperature-controlled, humidity-controlled, and otherwise filtered. Although discussed herein as having embodiments related to beds, in other embodiments, the disclosed air treatment systems and methods may be configured according to other types of furniture/sleep zones (e.g., chairs, couches, etc.).

In some embodiments, an air control device may be mounted to a bed in order to deliver compositionally controlled air to an occupant of the bed. A processing circuit can control the operation the air control device. For example, the processing circuit can generate the signals required to activate/deactivate the air control device, control fan speeds or directions of air flows generated by the device, adjust air temperature and other settings, etc. In some embodiments, sensors may be utilized to detect the position and/or orientation of the occupant, and treated air may be directed at the occupant based on the detected position and/or orientation of the occupant. In some embodiments, sensors may be used to detect conditions related to the occupant, and air may be treated and delivered based on the conditions. For example, a physiological state (e.g., temperature, sweat, respiration, heartbeat, oxygen saturation (SpO2), carbon dioxide exhalation amounts, etc.) of the occupant may be monitored, and the processing circuit may control delivery of air based on the occupant's physiological state. The various air control devices and configurations of such air treatment systems will be described in further detail below.

Referring to FIG. 1, a block diagram of an air treatment system 100 is shown, according to one embodiment. Air treatment system 100 includes air control device 102 and processing circuit 104. Air treatment system 100 may be configured to be coupled to a bed. In one embodiment, air treatment system 100 is mounted to a headboard, sideboard, baseboard, or bedframe of the bed. For example, air treatment system 100 may include various mounting features, such as clamps, hooks, bolts, etc., used to couple air treatment system 100 to the bed. In another embodiment, air treatment system 100 is integrated into the bed (e.g., within the headboard or throughout the bedframe). For example, a bed can be manufactured to include the air treatment system as described herein. Air control device 102 generally includes the components necessary to control a composition of air and deliver compositionally controlled air. For example, air control device 102 may include oxygen concentration devices, reservoirs for storage of gases fully or partially enriched with oxygen, carbon dioxide filtration devices, PSA (pressure swing adsorption) devices for nitrogen removal, etc. In one embodiment, air control device 102 includes one or more adsorptive materials (e.g., zeolites, activated carbon, molecular sieves, etc.) used to separate one or more target gas species. Air control device 102 may also filter air, adjust the temperature of air, add (e.g., for aromatherapy) or remove odorants and adjust the humidity of air. For example, air control device 102 may include one or more fans, filters, heating/cooling devices, humidifiers/dehumidifiers, piping, ducts, valves, compressors, an array of nozzles, etc. In some embodiments, air control device 102 may be configured to control the composition of air by adding additives to the air. For example, in one embodiment, air control device 102 may be configured to add inhalable stimulants, relaxants, or medicaments to the compositionally controlled air. Inhalable medicaments can include COPD treatments (e.g., Perforomist from Dey, AZD5423 from AstraZeneca, etc.), cough suppressants, a corticosteroid, bronchodilator, beta-blocker, anti-histamine, or other agents. Medicaments may be prescription drugs, over-the-counter drugs, neutraceuticals, or other agents. Inhalable medicaments may be delivered within the air as gas, as aerosols, or as powders. For example, inhalable stimulants may include caffeine, ammonia, Sports-Boost (available from Inhalex), Insufflalex HLE, or the like. Inhalable relaxants may be used as sedatives to help induce sleep, as muscle relaxants (e.g., for COPD, asthma, sleep apnea, environmental sensitivities, allergies, or other conditions), or the like. Inhalable sedatives, for example, may include any of those disclosed in German Patent Application No. DE 10130449, entitled “Inhalable sedative and hypnotic medicaments, e.g. containing benzodiazepine active agent, having high bioavailability and rapid action,” which is hereby incorporated by reference in its entirety. Inhalable muscle relaxants, for example, may include any of those disclosed by U.S. Pat. No. 7,507,397, entitled “Delivery of Muscle Relaxants Through an Inhalation Route,” which is hereby incorporated by reference in its entirety.

Processing circuit 104 controls the operation of air control device 102. Processing circuit 104 generates the signals necessary to cause air control device 102 to alter the composition of air delivered by air control device 102. For example, processing circuit may receive data related to a composition of source air (e.g., percentages of gases comprising the source air), and may determine adjustment amounts to be applied to the source air. Such data can be provided by sensors configured to detect components of air. As another example, processing circuit can monitor the temperature or humidity of source air, and may determine adjustments to be applied to the source air. In general, processing circuit 104 generates the signals required to interface with the various components of air control device 102 in order to control its operation.

Referring to FIG. 2, a block diagram of an air treatment system 200 is shown, according to one embodiment. Air treatment system 200 includes air control device 202 (which may be configured as air control device 102), processing circuit 204, and one or more position detection sensors 206. Air treatment system 200 may be configured to be coupled to a bed. In one embodiment, air treatment system 200 is mounted to a headboard, sideboard, footboard, or bedframe of the bed. In another embodiment, air treatment system 200 is integrated into the bed (e.g., within the headboard, sideboard, footboard, or frame). Air control device 202 generally includes the components necessary to control a property (e.g., composition, temperature, humidity, odor, filtration, etc.) of air and deliver the controlled air. Processing circuit 204 controls the operation of air control device 202 and causes the controlled air to be directed based on a detected position and/or orientation of an occupant of the bed. Processing circuit 204 can receive data from position detection sensors 206 (e.g., one or more cameras, wide-field-of-view cameras, RFID sensors, infrared devices, optical links, micro-impulse radars, ultrasonic sensors, mattress pressure/deflection sensors, temperature sensors, etc.), which are generally configured to provide data related to the position of an occupant of the bed. Accordingly, the occupant may be detected through analyzing the data provided by position detection sensors 206, which are able to sense the position of the occupant within the bed. Processing circuit 204 may determine a precise location and orientation of the occupant based on the data. In some embodiments, the orientation of an occupant may be estimated or inferred based on knowledge of human anatomy. For example, in an embodiment utilizing pressure/deflection sensors, different parts of the body produce different characteristics with respect to the pressure induced on the mattress of the bed, and by comparing various pressure points, the orientation of an occupant (e.g., the position of an occupant's legs, arms, back, etc.) can be determined Processing circuit 204 may also compare the sensor data to skeletal models and estimate an orientation of an occupant. Based on the determined position and/or orientation of an occupant, processing circuit 204 can adjust the positioning or output direction of air flow from air control device 202 (e.g., by adjusting fan positioning, nozzle positioning, fan speed, etc.) so that the air is directed at the occupant's general position (or more specifically toward the position of the occupant's head).

Referring to FIG. 3, a block diagram of an air treatment system 300 is shown, according to one embodiment. Air treatment system 300 includes air control device 302 (which may be configured as air control device 102), processing circuit 304, and one or more sensor devices 306. Air treatment system 300 may be configured to be coupled to a bed. In one embodiment, air treatment system 300 is mounted to a headboard, sideboard, footboard, or bedframe of the bed. In another embodiment, air treatment system 300 is integrated into the bed (e.g., within the headboard, sideboard, footboard, or bedframe). Air control device 302 generally includes the components necessary to control a property (e.g., composition, temperature, humidity, odor, filtration, etc.) of air and deliver the controlled air. Processing circuit 304 controls the operation of air control device 302 and causes the controlled air to be directed based on sensed conditions of the occupant of the bed. Processing circuit 304 can receive data from sensor devices 306 (e.g., one or more cameras, wide-field-of-view cameras, infrared devices, thermometers, gas detectors, functional near-infrared spectroscopy (fNIR) devices, electroencephalography (EEG) devices, Fluorescence spectroscopy devices, pulse oximeters, a pupillometer, an electromagnetic sensor, an electrical potential sensor, micro-impulse radars, light sensors, laser devices, and microphones, etc.), which are generally configured to provide data related to a condition of the occupant. Physiological sensors may include jewelry-embedded sensors, furniture-embedded sensors, as well as area-effect systems that use electromagnetic signals. Sensors used, for example, may include any of those disclosed in U.S. Patent Application Publication No. 2006/0058694 entitled “Electrodynamic sensors and applications thereof,” U.S. Pat. No. 7,245,956 entitled “Unobtrusive measurement system for bioelectric signals,” U.S. Pat. No. 7,272,431 entitled “Remote-sensing method and device,” and U.S. Patent Application Publication No. 2008/0045832 entitled “Remote-sensing method and device,” and C. J. Harland et al., 2003 Meas. Sci. Technol. 14 923-928, entitled “High resolution ambulatory electrocardiographic monitoring using wrist-mounted electric potential sensors,” which are hereby incorporated by reference in their entirety. Sensors 206 may be attached to the bed, worn by the occupant, or mounted elsewhere in the room. For example, sensor devices 306 may provide data related to a physiological condition of the occupant. In another example, sensor devices 306 may provide data related the SpO2 levels of the occupant. As another example, sensor devices 306 may provide data related to a sleep-state of the occupant. In another example, sensor devices 306 may monitor the breathing patterns or interruptions of the occupant. Accordingly, processing circuit 304 may analyze the data provided by sensor devices 306 and manage the delivery of controlled air by air control device 302 based on a determined occupant condition. In some embodiments, based on the data provided by sensors devices 306, air control device 302 may deliver more or less air, oxygen, or other medicaments, relaxants, or stimulants to the occupant. For example, air control device 302 may deliver more oxygen to the occupant if SpO2 levels drop below 85%.

Referring to FIG. 4, a detailed block diagram of processing circuit 400 for completing the systems and methods of the present disclosure is shown according to one embodiment. Processing circuit 400 may be processing circuit 104 of FIG. 1, processing circuit 204 of FIG. 2, or processing circuit 304 of FIG. 3. Processing circuit 400 is generally configured to control the operation of an air control device (e.g., device 102, device 202, or device 302), and processing circuit 400 may be the processing components of the air control device. For example, processing circuit 400 can generate the signals required to activate or deactivate the air control device and manage delivery of air. As another example, processing circuit 400 may generate the signals to communicate with components of the air control device in order to manage a composition of air to be delivered. Processing circuit 400 is further configured to receive sensor data and configuration and preference data. Input data may be accepted continuously or periodically. Processing circuit 400 may analyze the input data to determine the position and orientation of an occupant of a bed such that air may be directed toward the occupant. Processing circuit 400 may also analyze the input data to determine a condition of an occupant of a bed such that air may be delivered in response to stimuli related to the condition of the occupant. In controlling the operation of an air control device, in detecting the positioning of an occupant, and in determining a condition of an occupant, processing circuit 400 may make use of machine learning, artificial intelligence, interactions with local and/or remote databases and database table lookups, pattern recognition and logging, intelligent control, neural networks, fuzzy logic, etc.

According to one embodiment, processing circuit 400 includes processor 406. Processor 406 may be implemented as a general-purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a digital-signal-processor (DSP), a group of processing components, or other suitable electronic processing components. Processor 406 may be implemented as any commercially available processor. Processing circuit 400 also includes memory 408. Memory 408 is one or more devices (e.g., RAM, ROM, flash memory, hard disk storage, etc.) for storing data and/or computer code for facilitating the various processes described herein. Memory 408 may be or include non-transient volatile memory or non-volatile memory. Memory 408 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described herein. Memory 408 may be communicably connected to processor 406 and include computer code or instructions for executing the processes described herein.

Memory 408 includes memory buffer 410. Memory buffer 410 is configured to receive a data stream (e.g. from sensors 206 or 306, from a user input device, etc.) through input 402. For example, the data may include a real-time stream of sensor data, etc. The data received through input 402 may be stored in memory buffer 410 until memory buffer 410 is accessed for data by the various modules of memory 408. For example, air control module 414 can access the data that is stored in memory buffer 410.

Memory 408 further includes configuration data 412. Configuration data 412 includes data related to processing circuit 400. For example, configuration data 412 may include information related to interfacing with other components (e.g., sensors of systems 200 or 300, a user input device, etc.) and can include data required to configure communication between the various components of processing circuit 400. This may include the command set needed to interface with a computer system used transfer user settings or otherwise set up the system. This may further include the command set needed to generate graphical user interface (GUI) controls, menus, warning information, feedback, and visual information. As another example, configuration data 412 may include the command set needed to interface with communication components (e.g., a universal serial bus (USB) interface, a Wi-Fi interface, an Ethernet interface, etc.). Processing circuit 400 may format data for output via output 404 to allow a user to configure the systems as described herein. Processing circuit may also format visual information to be output for display on a display device. Processing circuit may also generate commands necessary to drive fans, compressors, motors, actuators, and other components of an air control device. Configuration data 412 may also include information as to how often input should be accepted from a sensor. Configuration data 412 may include default values required to initiate the air control device and initiate communication with sensors or other peripheral systems.

Processing circuit 400 further includes input 402 and output 404. Input 402 is configured to receive a data stream (e.g., a stream of data from sensors), configuration information, and preference information. Output 404 is configured to provide an output to an external system (e.g., a remote computer), an air control device, or other components of the systems as described herein.

Memory 408 further includes module 414 for executing the systems and methods described herein. Module 414 may access received sensor data, configuration information, user preference data, and other data as provided by processing circuit 400. Module 414 is generally configured to analyze the sensor data, detect a position and orientation of one or more occupants of a bed (or other furniture such as a couch, chair, etc.), determine a condition of one or more occupants, and control the operation of an air control device such that controlled air is delivered to the occupants. Module 414 may be further configured to operate according to a user's preferences. In this manner, air delivery characteristics may be adjusted according to a user's desires or a manufacturer's settings.

In one embodiment, processing circuit 400 is configured to control a bed mounted air control device in order to deliver air to an occupant of the bed. The air can be compositionally controlled in order to create a mixture containing certain percentages of gases. For example, the oxygen and carbon dioxide fractions of the air may be adjusted. These percentages may be based on user settings or configuration settings. The delivered air may be directed toward the head region of the occupant. For example, fans or output ports of air control device may be aimed at the head region of the occupant. In this manner, a direct, but unconstrained air flow may be provided. In one embodiment, the air is also filtered to remove particulate matter or other contaminants. In another embodiment, the air is also humidified or dehumidified in order to obtain a certain moisture level of the air. In another embodiment, the air is also heated or cooled in order to obtain a certain temperature of the delivered air.

In one embodiment, processing circuit 400 controls the air control device such that air flow delivered by the device is virtually constrained. For example, an output air flow may be configured to induce a gas curtain effect. Such an output can also include a differentiated peripheral flow of gas. The peripheral air flow may be treated in the same manner or in a different manner as a main air flow. Additionally, the peripheral flow may have a different velocity (e.g., higher or lower) and different direction than the main air flow. For example, the peripheral flow may be directed away from the area to which the main controlled air is directed (e.g., the peripheral flow may be directed such that it flows into ambient air). In one embodiment, to achieve such differentiated flow, the main and peripheral flows may be directed through different output components of the air control device. In another embodiment, a single output may be used that is configured to produce one or more differentiated air flows. Processing circuit 400 may also simultaneously control flow regulating components of the air control device in order to implement such a configuration.

In one embodiment, the air control device is configured to provide an air flow in a primarily vertical direction (i.e., downward) or in a primarily horizontal direction (i.e. parallel) with respect to the occupant. For example, the air flow may be from the head-side of the occupant towards the feet of the occupant. As another example, the air flow may be side to side (e.g., left to right, or right to left) over the occupant. In another embodiment, the air flow may be from the feet of the occupant toward the head of the occupant. Depending on the particular configuration of the system including the air control device, air may be delivered from various locations. The system may be built-in or may be an add-on unit. In one embodiment, air flow is delivered from the bedframe. For example, air delivery device (fans, piping, nozzles, etc.) may be embedded within the bedframe, mattress, suspension, or may be coupled to the bedframe. In this manner, air flow may be delivered from the headboard, sideboards, footboard, etc. In one embodiment, the air control device is configured to deliver an air flow that originates at or above a typical head level of the occupant. In another embodiment, the air flow may originate from the mattress, from the mattress level, or below. Any of the air flows described herein may be delivered to cover the full width of the bed or a portion of the bed. Additionally, the flows may be based on a detected position and orientation of the occupant.

In one embodiment, processing circuit 400 controls the air control device based on feedback. In this manner, the treatment of the air and air flow velocities/directions may be adjusted by processing circuit 400 in response to the feedback. One or more sensors may be used to provide such feedback, as will be described further herein. In general, the feedback may be related to the air as delivered to the occupant, sensed conditions related to the occupant (e.g., sleep state, physiological state, environmental conditions, etc.), or the positioning or orientation of the occupant. Based on the feedback, processing circuit 400 may drive the air control device in order to reach or maintain target values (e.g., a target temperature, a target air flow rate, a target humidity level, etc.). The target values may be constant or may be specified by a schedule. For example, at a certain time, a fast and warm flow of compositionally controlled air may be desired, and at a different time, a slower flow of cooled air may be desired. Such a schedule may be defined and stored as a configuration setting (e.g., stored in configuration data 412, etc.). In one embodiment, target values are based on an ID or preferences for the occupant. The target values and preferences may be stored in a user profile for the occupant. As an example, the air control device may include an RFID tag reader capable of detecting an RFID tag of the occupant. Processing circuit 400 may communicate with the RFID tag reader to identify a particular occupant based on the RFID tag information. As another example, the occupant can be identified by physical characteristics (e.g., weight, size, facial features, respiration pattern, etc.). As another example, the air control device may be configured for wireless communications (e.g., via Wi-Fi, Bluetooth, etc.). An occupant's identification may be transmitted to the air control device via a wireless connection when the occupant desires, or automatically when the occupant nears the bed. In this manner, after identifying the particular occupant, processing circuit 400 may then access a profile for the occupant and set target values and other device preferences based on the profile.

In one embodiment, processing circuit 400 is configured to control a bed mounted air control device that delivers air to an occupant of the bed, where the air is delivered based on a detected position and/or orientation of the occupant. Processing circuit may receive positioning data from a variety of sensors of the air control device. The sensors may be mounted to the bed or the air control device. For example, the sensors may include mattress pressure or deflection sensors. In this manner, the position of the occupant can be determined by analyzing the pressure/deflection data to detect when an occupant is in the bed. Further, the location of the sensors and the pressure gradient across the mattress can be further analyzed to determine the location and orientation of the occupant. For example, different parts of the human body induce different pressures on the mattress. In another example, temperature sensors in the bed (e.g., in a mattress pad) can be monitored to determine the location and orientation of the occupant. Accordingly, the location of an occupant's head, mid-section, and feet, can be estimated based on the sensor values. As another example, the sensors may include one or more remote sensors (e.g., micro-impulse radar, cameras, ultrasonic sensors, thermal imagers, etc.). A stream of sensor data can then be monitored to determine when and where an occupant is on the bed. For example, a feed from a camera can be analyzed to detect the presence of an occupant. The camera data can also be further analyzed to determine the location and orientation on the bed with respect to the camera. Based on this analysis, processing circuit 400 can determine in which direction the compositionally controlled air should be delivered such that it is aimed at the occupant. Processing circuit 400 can generate the appropriate signals to adjust the directional output of the air control device. For example, the direction of fans, nozzles, vents, or other air flow control devices may be adjusted.

In one embodiment, control of the air control device by processing circuit 400 is triggered by one or events. Any of the sensors described herein may provide data signals that trigger the operation of the air control device. For example, the air control device may be triggered by the presence of an occupant, by a light level, according to a schedule, etc. In an embodiment utilizing cameras, the camera data may be analyzed by processing circuit 400 to determine the presence of an occupant, and when an occupant is detected, further operation of the air control device may be triggered. This may include activating or deactivating an air flow, position an air flow, adjusting a flow rates, adjusting a temperature or humidity level of an air flow, altering a composition of the air of an air flow, etc. In an embodiment utilizing pressure sensors, a certain detected pressure may trigger such control of the air control device. For example, processing circuit 400 may automatically begin to control the device when a pressure of at least 50 pounds is detected on the mattress of the bed. In an embodiment utilizing micro-impulse radar, a detected motion or proximity of an occupant may trigger such control of the air control device. For example, processing circuit 400 may automatically begin to control the device when a motion is detected within a few feet from the air control device. In an embodiment utilizing a light sensor, a detected level of light may trigger such control of the air control device. For example, processing circuit 400 may automatically begin to control the device when the light level is that of typical sleeping conditions. For example, processing circuit 400 may automatically begin to add a stimulant to the air 30 minutes before the occupant is scheduled (e.g., based on an alarm clock, an electronic calendar, etc.) to wake up.

In one embodiment, processing circuit 400 is configure to control a bed mounted air control device that delivers air to an occupant of the bed, where the air is delivered based on one or more sensed conditions related to the occupant. In one embodiment, the sensed conditions are physiological-related conditions. For example, a condition may include the temperature of the occupant and/or the environment surrounding the occupant. In this manner, processing circuit 400 may control and configure the air control device based on temperature. As another example, the condition may include detected sweat (perspiration) from the occupant. In this manner, processing circuit 400 may control and configure the air control device based on whether the occupant is sweating (e.g., processing circuit may cause a temperature of an air flow to decrease if the occupant is exhibiting signs that he or she is hot, etc.). As another example, the condition may include detecting respiration characteristics of the occupant. In this manner, processing circuit 400 may control and configure the air control device based on the respiration of the occupant (e.g., processing circuit may adjust the composition of an air flow based on one or more respiration characteristics, etc.). As another example, the condition may include detecting heartbeat characteristics of the occupant. In this manner, processing circuit 400 may control and configure the air control device based on the pulse of an occupant. As another example, the condition may include detecting exhalation characteristics (e.g., a carbon-dioxide amount, etc.) via data from sensor devices. In this manner, processing circuit 400 may control and configure the air control device based on the contents of what the occupant is exhaling. In another embodiment, the sensed conditions are related to a sleep-state of the occupant, and processing circuit 400 may control and configure the air control device based on any of these conditions. For example, a condition may be whether the occupant is asleep or awake. As another example, a condition may include a REM-pattern of the occupant. As another example, the condition may include whether the occupant is snoring. As another example, the condition may include a breathing pattern. As another example, the condition may include physical movements of the occupant during sleep.

The conditions discussed above may be detected utilizing a variety of sensors that supply data to processing circuit 400. The sensors may be part of the air control device, or the sensors may be remote. In a remote configuration, such sensors may provide data to processing circuit 400 via a wired or wireless connection, and processing circuit 400 may analyze the data in order to detect a condition. Sensors may include a visible or infrared camera, a pulse oximeter, a thermometer, a gas detection sensor, a functional near-infrared spectroscopy (fNIR) device, an electroencephalography (EEG) device, a Fluorescence spectroscopy device, micro-impulse radar, a laser, and/or a microphone.

In any of the configurations disclosed herein, air may be delivered to multiple occupants of a bed. For example, processing circuit 400 may utilize the techniques discussed above to detect the location and orientation of multiple occupants and the conditions related to the multiple occupants. When multiple occupants are present, the same air flow or differentiated air flows may be provided to each of the occupants. In embodiments where multiple different air flows are provided, the corresponding air control device may include air supply components that are independently controllable by processing circuit 400 such that different air flows may be simultaneously generated. Alternatively, the components of the air control device may be toggled between multiple occupants, and processing circuit 400 may manage the configuration of the air control device as it toggles such that each occupant receives a particular air flow.

Additionally, in any of the configurations disclosed herein, the air control device may include an articulating boom that can be used to deliver an air flow (e.g., via an outlet of the boom) to an occupant of a bed. For example, in an embodiment where processing circuit 400 uses sensor data to detect the location and orientation of the occupant, the articulating boom may be automatically positioned based on the location of the occupant. For example, such an articulating boom may include various motors or actuators that can be controlled by processing circuit 400 in order to position the boom. In one embodiment, the articulating boom also includes any of the sensors discussed herein. For example, the articulating boom may include sensors configured to provide data related to the location and orientation of an occupant. As another example, the articulating boom may include sensors configured to provide data related a condition of the occupant. In one embodiment, the articulating boom also includes an air intake, which can be used to supply source air to compositionally controlled and otherwise adjusted by the air control device. Such an air intake may also be used to provide air used to detect exhalation characteristics of a bed occupant.

In one embodiment, air delivery mechanisms 508 include conduit that is embedded throughout the frame of bed 502 such that an air flow of compositionally controlled air may be delivered to an occupant of bed 502 at various locations and at various air flow configurations. For example, an air flow may be directed through the mattress of bed 502, or from the footboard area of bed 502. Processing circuit 506 may be configured to communicate with one or more sensors as disclosed herein. For example, pressure sensors 510 may be embedded in the frame or mattress of bed 502. Based on data from sensors 510, processing circuit 506 may detect the position and orientation of an occupant of the bed, and control the operation of air control device 506 based on the position and orientation. For example, processing circuit 506 may adjust the orientation of fans 508 (e.g., via controlling actuators of the fans, etc.) in order to obtain a desired air flow. As another example, an EEG device 514 may be worn by the occupant of the bed as he or she sleeps. EEG device 514 may provide data to processing circuit 506 so that processing circuit 506 can detect conditions related to the occupant, and adjust the operation of air control device 504 based on the conditions.
